get_list

Gets details of a ClickUp list. Use listId (preferred) or listName. Returns list details including name, content, and space info. ListId more reliable as names may not be unique.

add_tag_to_task

Adds existing tag to task. Use taskId (preferred) or taskName + optional listName. Tag must exist in space (use get_space_tags to verify, create_space_tag if needed). WARNING: Will fail if tag doesn't exist.

move_bulk_tasks

Moves multiple tasks to one list. For each task: use taskId (preferred) or taskName + listName. Target list: use targetListId/Name. Configure batch size/concurrency via options. WARNING: Task statuses may reset, taskName needs listName.

attach_task_file

Attaches file to task. Use taskId (preferred) or taskName + optional listName. File sources: 1) base64 + filename (≤10MB), 2) URL (http/https), 3) local path (absolute), 4) chunked for large files. WARNING: taskName without listName may match multiple tasks.

find_member_by_name

Finds a member in the ClickUp workspace by name or email. Returns the member object if found, or null if not found.

get_workspace_tasks

Purpose: Retrieve tasks from across the entire workspace with powerful filtering options, including tag-based filtering. Valid Usage: 1. Apply any combination of filters (tags, lists, folders, spaces, statuses, etc.) 2. Use pagination to manage large result sets 3. Include subtasks by setting subtasks=true Requirements: - At least one filter parameter is REQUIRED (tags, list_ids, folder_ids, space_ids, statuses, assignees, or date filters) - Pagination parameters (page, order_by, reverse) alone are not considered filters Notes: - Provides workspace-wide task access (unlike get_tasks which only searches in one list) - Returns complete task details including descriptions, assignees, custom fields, and all metadata - Tag filtering is especially useful for cross-list organization (e.g., "project-x", "blocker", "needs-review") - Combine multiple filters to narrow down your search scope - Use pagination for large result sets - Set subtasks=true to include subtask details in the response IMPORTANT: subtasks=true enables subtasks to appear in results, but subtasks must still match your other filter criteria (tags, lists, etc.) to be returned. To see all subtasks of a specific task regardless of filters, use the get_task tool with subtasks=true instead. - Use the detail_level parameter to control the amount of data returned: - "summary": Returns lightweight task data (name, status, list, tags) - "detailed": Returns complete task data with all fields (DEFAULT if not specified) - Responses exceeding 50,000 tokens automatically switch to summary format to avoid hitting LLM token limits - **Enhanced List Filtering**: When list_ids are provided, the tool leverages ClickUp's Views API to include tasks that are *associated with* the specified lists, including tasks that have been added to multiple lists. This provides comprehensive coverage of all tasks related to your specified lists, not just tasks that were originally created in those lists.

start_time_tracking

Starts time tracking on a task. Use taskId (preferred) or taskName + optional listName. Optional fields: description, billable status, and tags. Only one timer can be running at a time.

remove_tag_from_task
